um... the easy answer is that i don't sleep.
which gets really old when all you want to do is be done with a day.
But i haven not been able to sleep a day without my sleeping pill/tranquilizer since the middle of April when i got out of jail.
It bothers me just cuz i'm totally dependant on the drug now, and now it doesn't even make me sleepy (though it is still at least allowing me to go and stay asleep)
but to answer your question, on the nights that i don't take the drug, i pretty much do something very mundane until i realize i'm sleepy. That is, i'll play an online game, or read a book, or write. The moment i think i'm even a little sleepy, i jump into bed, and depending on the mooc i'm in, i'll either make it completly quiety, or i'll turn on the tv for background noise.
it sucks when sleep is illusive. I'm sorry.
I hope that people will check in and give you better feed-back--- like people that haven't had to deal with insomnia for years (i had flare-ups before last April).
good luck!
